 ## Contributing to library of epidemiological parameters
 
-If you would like to contribute to the different epidemiological
-parameters stored in the `{epiparameter}` package, you can add data to a
-public [google
-sheet](https://docs.google.com/spreadsheets/d/1eCL3n_woseg5Npu7XD7TcuNoLUIhMBu8ZoLCkVdATUE/edit?usp=sharing).
-This spreadsheet contains two example entries as a guide to what fields
-can accept. We are monitoring this sheet for new entries that will
-subsequently be included in the package.
-
-Alternatively, parameters can be added to the [JSON file holding the
-data](https://github.com/epiverse-trace/epiparameter/blob/main/inst/extdata/parameters.json)
-base directly via a Pull Request.
-
-You can find explanation of accepted entries for each column in the
-[data
-dictionary](https://github.com/epiverse-trace/epiparameter/blob/main/inst/extdata/data_dictionary.json).
+The library of epidemiological parameters that can be loaded by
+`{epiparameter}` using the `epiparameter_db()` function is stored in the
+[`{epiparameterDB}` R
+package](https://github.com/epiverse-trace/epiparameterDB). If you would
+like to contribute to the library of epiparameters you can either:
+
+1.  Add data to a public [google
+    sheet](https://docs.google.com/spreadsheets/d/1eCL3n_woseg5Npu7XD7TcuNoLUIhMBu8ZoLCkVdATUE/edit?usp=sharing).
+    This spreadsheet contains two example entries as a guide to what
+    fields are accepted. We are monitoring this sheet for new entries
+    that will subsequently be included in the package.
+
+2.  Add to the [JSON file holding the
+    database](https://github.com/epiverse-trace/epiparameterDB/blob/main/inst/extdata/parameters.json)
+    directly via a Pull Request. See the [contributing
+    guide](https://github.com/epiverse-trace/.github/blob/main/CONTRIBUTING.md)
+    for instructions.
+
+You can find a description of the epidemiological parameter data
+structure and contents in the [data
+dictionary](https://github.com/epiverse-trace/epiparameterDB/blob/main/inst/extdata/data_dictionary.json).
+This documents the valid format and data types to ensure consistency and
+accuracy. All entries in the parameter library are automatically
+validated against the data dictionary using an GitHub action workflow.
